Well basically my heaters are smoking not major but enough for me to turn them off and there is a slight smell of burning while they are on, the heater does heat the car fully like it always has but just lately there has been major condensation issues.

I have also noticed in the engine bay that one of the hose's from the heater matrix has been leaking onto the engine, I have also checked the foot wields to see if there is any coolant leaking but its bone dry.
